Today, the first grow tube went into service.

The grow tube is about 15ft long and holds 27  four inch pots. Water from tank #2 is circulated through the tube and returned to the tank.

Inside the tube is the same rock media that is used in the grow beds. Each of the four inch pots is also filled with this media. The pots rest on the rock, allowing a water depth in the pots of approximately 3/4 of an inch.

The tube is attached to the edge of the grow beds using pieces of recycled metal banding.
I ordered more fish today. They are to be here Friday. I am getting another 100 hybrid Bluegil, and 100 channel catfish.
